Abstract

Heat distortion temperature of polyvinyl chloride compositions can be significantly increased above the heat distortion temperature of uncompounded polyvinyl chloride by preblending an imidized acrylic resin having a glass transition temperature above 140 °C with a third polymer melt-processable throughout the temperature range of 150-300 °C under conditions where a two-phase blend is formed, wherein the third polymer forms the continuous phase and the imidized acrylic resin forms the dispersed phase and then melt-blending the two-phase blend with polyvinyl chloride at a temperature of 150-220 °C to form a composition in which the imidized acrylic resin forms a substantially homogeneous blend with polyvinyl chloride. It also is possible to preblend imidized acrylic resin with a third polymer with which it is compatible, for example, another imidized acrylic resin having a sufficiently low glass transition temperature to lower the resulting glass transition temperature of the preblend below about 130 °C, which then is blended with polyvinyl chloride.
